Longnose pliers can be used for cutting and holding of fine wires and they can be used in tight space, these types of pliers are commonly used for making terminal loops in copper wire.
Diagonal pliers are used for cutting medium or fine wires they are also used in bending small faces of soft metal. Wire strippers are used to remove the insulation of wires, mostly medium-sized wires ranging from gauge 10 to gauge Wire strippers are also used to remove the insulation of rubber covered wires from gauge 26 to gauge These knives are used by lineman to remove the insulation of big cables in high and low voltage transmission lines. Screwdrivers can be used to loosen or tighten screws with slotted heads, screwdrivers are in various size and shape.
Screwdrivers are made up of steel and they are tempered at the tip. According to the size and shape of screw different types of screwdrivers are used. Hammers are tools which are used for pounding and pulling out of nails, there are soft and hard-faced hammers. Hard faced hammer can be used to strike hard objects and they have a cylindrical-shaped head.
The soft-faced hammer is used for the rewinding process. Mostly soft-faced hammers are made up of rubber or plastic.

Conduits embedded into the walls shall be fixed by means of staples at not more than 60 cm intervals. Chase in the wall shall be neatly made and refilled after laying the conduit and brought to the finish of the wall. Conduits buried in concrete structure shall be put in position and securely fastened to the reinforcement and got approved by the consultant before the concrete is poured.
Proper care shall be taken to ensure that the conduits and boxes are neither dislocated nor choked at the time of pouring the concrete. Inspection boxes shall be provided for periodical inspection to facilitate draw and removal of cables. Such inspection boxes shall be flush with the wall in the case of recessed conduits. Inspection boxes shall be spaced at not more than 12 meters apart or two 90 degree solid bends or equal.
Use of PVC conduits in places where ambient temperature is 60 degree c or above is prohibited. PVC conduits shall not be used in outdoor system. Conduits shall be free from sharp edges and burrs and grease or oil shall not be used for the purpose of pulling the wire. The entire system of conduits must be completely installed and rendered electrically continuous before the conductors are pulled in. All joints shall be water tight. Junction between conduit and adaptable boxes, back outlet boxes, switch outlet boxes and the like must be provided with entry spouts and smooth PVC bushes.
A voltage tester is used for a quick safety check to make sure there's no voltage in an electrical wire or device before you start working on it.
Non-contact voltage testers, powered by batteries, are the simplest and safest types of testers because they can detect electricity just by being near an outlet slot or wire. This is a tool every DIYer needs in the toolbox. It will be used for virtually every home electrical repair project. Another essential electrical specialty tool for homeowners is a good pair of wire strippers.
Wire strippers are used to cut and strip insulation from electrical wires. A wire stripper tool has a row of gauged holes for stripping wires of different sizes, and it usually includes cutting jaws for trimming the wire ends. Some types are combination tools that can also be used to crimp wires and to strip the vinyl jacket off NM cable. Along with a voltage tester, this is perhaps the most important specialty electrical tool you can own.
It makes sense to invest in a good set of wire strippers, as it will serve many functions. Another essential specialty electrical tool is a pair of needle-nose pliers also called long-nose pliers. It will be used for bending and twisting wires whenever you are making screw-terminal connections.
The long, narrow tip makes this a great tool for detailed work. Most needle-nose pliers also include cutting jaws for trimming wires. A pair of linesman pliers is an electrician's do-it-all tool. It has a squared-off end that is great for twisting wires together, a center cutting blade for trimming wire, and a grip area between the handles for pulling wire.
Casual DIYers may be able to get by without this tool, but anyone who does regular electrical work will want to own a pair of linesman pliers. Diagonal cutting pliers, sometimes called side snips or dikes, are used to cut wires.
They are specially designed with a cutting edge that goes down to the tip of the jaws, allowing you to get into tight areas to trim wires. Some types can also have a built-in voltage detector to sense live wires. You can also find combination tools that include wire-stripping slots built into the handles. This is a second-tier specialty tool: Casual DIYers may not need it, but those who do regular electrical work will find it very useful.
A fish tape is used to pull stranded or solid wire conductors through metal or PVC conduit. Cable lube is available to assist you in pulling the wires through the conduit. A fish tape can also be helpful when you are pulling NM cable through wall cavities.
This is a tool used when making wiring improvements, such as adding or extending circuits. An electrician must know the important electrical tools names which are used in the wiring, construction and troubleshooting electric works.
In this article, I am going to introduce some an important electrical tools with pictures. Read completely to know an each one of the electrical tool uses. We used to work with lot of tools when working on field side. But this time, we will see only an important electrical tools which is used for electrical installation. To complete the electrical works, we need a few specialty tools as well as a collection of basic hand tools.
As with any tool purchase, invest in quality products when we buy tools for electrical work. We need to keep those clean, and sharpen or replace any cutting tools that have dull edges. The materials used for electrical work have changed dramatically in the last 20 years, making it much easier for consumers to do their own electrical work.
The following tools are used in the electrical wiring works. Insulation Tapes: A material of electrical tapes in a variety of colors are used for marking wires and for attaching cables to a fish tape.
